Sean Spicer Resigns

Sean Spicer, the White House press secretary, resigned on Friday morning, after denouncing chaos in the West Wing and telling President Trump he vehemently disagreed with the appointment of the New York financier Anthony Scaramucci as communications director.

Mr. Trump offered Mr. Scaramucci the job at 10 a.m. The president requested that Mr. Spicer stay on, but Mr. Spicer told Mr. Trump that he believed the appointment was a major mistake, according to a person with direct knowledge of the exchange.

A spokeswoman for the president, Sarah Huckabee Sanders, was elevated to press secretary.
